Asymmetric flux pinning in laterally nanostructured ferromagnetic / superconducting bilayers
M. Lange, M. J. Van Bael, L. Van Look +5
We investigated the pinning of flux lines in a superconducting film by a regular array of magnetic antidots. The sample consists of a Co/Pt multilayer with perpendicular magnetic a…
Flux pinning by regular arrays of ferromagnetic dots
M. J. Van Bael, L. Van Look, K. Temst +6
The pinning of flux lines by two different types of regular arrays of submicron magnetic dots is studied in superconducting Pb films; rectangular Co dots with in-plane magnetizatio…
Nucleation of Superconductivity in a Mesoscopic Loop of Finite Width
V. Bruyndoncx, L. Van Look, V. V. Moshchalkov
The normal/superconducting phase boundary Tc has been calculated for mesoscopic loops, as a function of an applied perpendicular magnetic field H. While for thin-wire loops and fil…
Flux pinning in a superconducting film by a regular array of magnetic dots
L. Van Look, M. J. Van Bael, K. Temst +4
We have studied flux pinning in thin superconducting Pb films covering a triangular array of submicron magnetic Au/Co/Au dots with in-plane magnetization. The rectangular dots can…
Shapiro steps in a superconducting film with an antidot lattice
L. Van Look, E. Rosseel, M. J. Van Bael +3
Shapiro voltage steps at voltages V_n=nV_0 (n integer) have been observed in the voltage-current characteristics of a superconducting film with a square lattice of perforating micr…
Dimensional crossover in a mesoscopic superconducting loop of finite width
V. Bruyndoncx, L. Van Look, M. Verschuere +1
Superconducting structures with the size of the order of the superconducting coherence length xi(T) have a critical temperature T_c, oscillating as a function of the applied perpen…
